DESCRIPTION
The LM628/LM629 are dedicated motion-control processors designed for use with a variety of DC and brushless
DC servo motors, and other servomechanisms which provide a quadrature incremental position feedback signal.
The parts perform the intensive, real-time computational tasks required for high performance digital motion
control. The host control software interface is facilitated by a high-level command set. The LM628 has an 8-bit
output which can drive either an 8-bit or a 12-bit DAC. The components required to build a servo system are
reduced to the DC motor/actuator, an incremental encoder, a DAC, a power amplifier, and the LM628. An
LM629-based system is similar, except that it provides an 8-bit PWM output for directly driving H-switches. The
parts are fabricated in NMOS and packaged in a 28-pin dual in-line package or a 24-pin surface mount package
(LM629 only). Both 6 MHz and 8 MHz maximum frequency versions are available with the suffixes -6 and -8,
respectively, used to designate the versions. They incorporate an SDA core processor and cells designed by
SDA.
